Consider blogs. Their great wonder is their dynamic speed. We are exposed to many more ideas than previously possible and given a chance to dialogue in near real-time. Yet because of their brevity and the constant evolution of content, blogs are forced to stay on the surface. Blogs are ill-suited for deep level analysis and thoughtful reasoning. The Internet makes a flat stone of the mind and skips it across the surface of the world's information ocean. A book, by contrast, is a sturdy submarine diving the mind deep into the sea.
